companying drawings, forming a part of this specification, and to thereferencenumerals marked thereon.

The present inventionrelates to printing apparatus and it has for itsobject to provide an improved machine for printing limiting amountindicating characters on negotiable instruments, I such as checks,drafts, or bonds -to prevent the original amount written in the body ofthe instrument from being fraudulently increased, or raised.

Our invention has for its further object to provide means whereby thenumerals or amount'indicating characters and the symbols employed inconnection-therewith and located at the ends of the printed amount maybe rinted' in inks of diiferent colors, or of di erent composition, toperform the dual purpose of giving distinctness to the amount indicatingcharacters themselves and also to effectively thwart prefixing orsuilixing other amount indicating characters to those previously appliedto the instrument.

To these and other ends' the invention con-' sists in certainimprovements and combinations of parts all as will be hereinafter morefully described, the novel features being pointed out in the claims atthe end of the specification.

is a top view of the work feeding mechanism detached. Fig; 10 is a sideview of the work feeding mechanism detached, and Fig.

11 is a bottom view. of the overhanging -instruments, it is apparentthat some of'its features may be adapted for other printing apparatus.In the resent embodiment a c ieck, draft or the like is clamped upon asuitable work support, its position being determined by suitable gagesand a scale. After each imprint of a character the work is automaticallyfed on the support and when the amount is filled in and the operatingmeans is moved to a certain position, the work is automaticallyreleased. The characters denoting. the currency of different countriesand a character ,indicating the end of the printed amount in order toprevent the addition of other figures, are printed in an ink of adifferent color from that in which the amount indicating characters areprinted, so that it is impossible to print over these characters withoutmaking the change apparent. The indicating means "for the printingmechanism is so located that it is not covered by the work.

The present embodiment comprises a printing mechanism preferablyconsisting of a platen 1 and a type or printing wheel 2 operated by asuitable shiftin means, the type wheel for this purpose icing, ifdesirable, mounted on the forward end of a horizontally arranged shaft 3provided at its rear end with a bevel gear a to mesh with a like gear 5on a vertical shaft 6. Vertical-shaft 6 may carry at its lower end agear 7 with'which may mesh an arcuate rack 8 on a horizontally swingingmember or frame 10, whereby drivingconnection between the frame'andprinting wheel is established. In this embodiment the swinging member orframe is supported within a casing which incloses most of the parts ofthe appliance and comprises east side walls,

the front one of which has a horizontal slot, the portion 11 of thiswall below the ing. A headed bolt: 14 is passed upwardly through frame12 and through the bearing sleeve 15 of the swinging member, and nutthereon to turn about a horizontal axis and projectsthrough thehorizontal slot in the casing, its outer end being provided with a knob17 by which it may be depressed into any one of a number of recesses ornotches 1 8 formed in one wall of the horizontal slot. v

The platen in the present instance is moved toward the type wheel andfor this purpose the rear end of the arm 16 may carry an anti-frictionball 19 to cooperate with the platen and moves it around a pivot 21 withthe arm 20, by which it is rigidly carried. The pivot points of the arm16 and the arm 20 are shiftable, the former for the purpose of obtainingproper pressure on the laten, and the latter in order that the ridgesormed on the impact face of the platen may be made to engage between theridges forming the type on the printing wheel, so that f the paper maybe perforated.- In this embodiment the pivot 22 of the arm 16 is car--ried by a frame or member 23vertically adj ustable by swinging about ahorizontal pivot 24 on the horizontally swinging member 10, the member23 being held in different positions by an adjustable stop 25 and anadjusting screw 26; while the pivot pin 21 is carried bya swinging frameorlink 27,

which 'is' held in different positions by an adjustable stop 28 and anadjusting screw 29.

The frame or link 27 is preferably carried by a frame 30 which alsocarries the type or printing wheel 2, its horizontal shaft 8 andvertical shaft 6, the frame 30 being. bolted at 31 to the casing nearthe rear of the latter, and having a depending portion that projectsinto the casing through'an opening,

32 and carries the vertical shaft 6 and the platen supporting link 27.This frame incloses the gears 4 and 5 and projects forwardly over thetop 33 of the casing, while.

its forward end is recessed to house the printing wheel and the inkingmechanisms to be described, a removable transparent plate 30 serving toclose the recessed end and permit the inspection and cleaning of theparts therein.

' The top 33 of the casing is removable and serves as a work support,being located a slight distance below the lowermost type on the printingwheel and provided with an opening 34- through which the hammer platen 1is adapted to pass. Except when the support to determine the position ofthe work are gages 5 which are adjustable forwardly and rearwardly overscales 35 by 7 means of clamping screws 36 working in slots 87. A scale69 extends in the direction of the feeding of the work on the supportandserves to determine theposit ionfor the end of the check or the like inordeF that the operator may allow suflicient distance thereon in whichto print the numberof characters necessary to indicate a given amount.This scale is also arranged so thatthe last character of the amount willlie in proximity to the right hand margin of the check.

h The impact face of the platen and the printing face of the type aremade of metal and cut the fiber of the paper which is also supplied withindelible ink that is fed to the type by a suitable inking mechanism.

As in printing checks, drafts or the like, it is desirable that thesymbols for the systems of currency of the different countries beprinted in a different color from the amount, so that changes bysuperimposing are rendered practically impossible, two inking elementsare preferably employed, one being thrown automatically to a position tocooperate with certain type, while the other is thrown auto natically toa position to cooperate with other type. The inking mechanism comprisestwo inking elements preferably in the form of twowheels 37 and 37*, eachhaving an inking surface 38, which, when moved into engagement with thetype wheel, rotates by contact therewith. Each wheel is mountedpreferably on a single movable frame or housing 39, pivoted at 40 andnormally tending to move toward the printing character under action ofsprings 43. They are moved .from the printing wheel by a suitable devicewhich preferably embodies two sets of cams or projections 41 and 42 Inorder to determine the type to be printed, there may be'employed asuitable indi-' cating means which'is preferably located above the worksupport so that it willnot be rendered obscure by the work. In thepresent instance an indicating plate 43 having the characters arrangedthereon in the order of those ,on the type wheel, is positioned ontheforward port-ion of the overhanging frame 30 above the' work support,while a pointer or index 44 is bolted to a. gear segment 45 pivoted onthe rear portion the elevation of "the pla en the dog 54; rides of theframe 30, said gear segment being meshed with a pinion 46 on the upperportion of the vertical shaft 6, so that when the handle or arm 16 isswung the pointer will move in accordance therewith.

After each impression of the type the work is advanced by a suitableworking feeding mechanism which preferably comprises a rotary element orwheel havingtwo spaced roughened portions 47 projecting slightly abovethe top surface of the casing or work support. This rotary element turnson a pin 48 carried by a frame 49 that is bolted to the under surface ofthe top of the casing. This frame 19 may also carry a swinging ever 50turning about a pivot 51 and normally held in the lower position" by aspring 52, an adjustable stop 53 on the frame 49 acting to limit itsmovement under the action of the spring. Lever 50 has pivoted thereto adog the elevation of the lever the latter is provided with an offsetarm57 engaged by a lateral extension 58 on the arm 20 carrying theplaten; and by this means when the platen drops or is moved away fromthe type wheel .the work will be fed forward one space to receiveanother impression, and, on

over the ratchet wheel.

Cooperating with the feeding device is a clamping device controlled bythe shifting means. This device preferably embodies a roller 59 suitablyjournaled on the arm 60 extendin I '61 exten s longitudinally of theframe and Lee at its rear end carries a depending L- shaped arm 62, thefree end. of which is formed with a depending beveled portion 63 withWl'llCh cooperates a rearward extension 64 on the horizontally swingingmember or frame10' in order to effect the elevation of the roller 59 andthe releaseof the Work when the arm 16 ismoved to release position, thisposition being indicated on the dial at 65. 'A spring 66 connecting theeasin and the arm servesto'move the rollerlt'o c aiuping position.

Generally stated, theo eration of the invention is as follows: \llfiil'e the arm 16 is in release position, a check, draft or the like isfitted beneath the type wheel, against the gages 35-and with a side edgealined with one of the divisions or scale 69'corresponding to the amountto be printed. The arm 16 is now swung until the index 44: points to the'symbol to indicate the currency (55, :9, M,

F or, R) and is then depressed to move the platemagainst the type wheel,causing the symbel to be printed in ink of one color.v

froma rock shaft 61. Rock shaft- With the elevation of the arm the workis fed one step and then the amount is printed in another color, bysuccessive swinging movements and depressions of the arm. After theamount has been completed, the symbol 67 which occurs last on the dial,is printed in the color of the symbol of the currency in order toprevent the addition of other characters to raise the amount of thepaper, and then the arm is moved to release position to free the paperby moving the clamp.

An apparatus constructed in accordance with this invention will so markcommercial paper that fraudulent raising of the same will be prevented.It insures the proper positioning of the characters on the paper andfacilitates the work of making checks, drafts or the like by having allof the movements of the apparatus controlled by a single lever.
